Your wedding will go by FAST. And chances are, you'll hardly remember it, because it will feel like you are in a really good dream, full of all the people you love and nothing but happiness.  A photographer will have photos of the basics to show you what happened. A GREAT photographer will capture moments you didn't even KNOW happened (tears, laughs, booty grabbing), and most importantly use artistic methods to remind you of how it FELT on your wedding day. Wedding photography is an investment and it buys you a time machine.
